  engineers use d²π/4 as you can’t measure the radius of a pipe or a similar 3d solid object only diameter.

    or engineers are not smart enough to calculate r=d/2 first

      Why would i calculate r? I need only the area. See? Why would I waste my time for an extra calculation.

        Just do it in your head? The diameter is 5.62, so the area is π2.81², which is more efficient to type in your calculator than π5.62²/4. You’re the one wasting time.

      You just imported a point cloud, so you can’t snap to the centerline, you measure the diameter.

    This actually explains some of the formulas in research papers I’ve read.

  No its actually r^2π

    No, its r^π √2
